Description

Kühlvorrichtung, insbesondere für die abzudichtenden Stellen von umlaufenden Wellen Die Erfindung betrifft eine Kühlvorrichtung, insbesondere für die abzudichtenden Stellen von umlaufenden Wellen, nach .dem Hauptpatent 475 253 und besteht darin, daß das Kühlmittel von der Welle her in einen zwischen der Welle und einer sie einhüllenden Büchse vorgesehenen Hohlraum eingeführt wird. Sind mehrere zwischen der Welle und der sie einhüllenden Büchse gebildete Hohlräume vorhanden, so wird das Kühlmittel in bekannter Weise vorteilhaft in den innersten Hohlrauen eingeführt und aus dem äußersten Hohlraum abgeleitet.Cooling device, in particular for the areas to be sealed off Shafts The invention relates to a cooling device, in particular for the ones to be sealed Setting of rotating shafts, according to the main patent 475 253 and consists in that the coolant from the shaft into one between the shaft and one enveloping it Bushing provided cavity is inserted. Are several between the shaft and there are cavities formed in the sleeve surrounding it, the coolant becomes in a known manner advantageously introduced into the innermost hollow roughness and out of the outermost cavity derived.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist -auf der Zeichnung an Hand einer für Heißwasserpumpen zu verwendenden Stopfbüchse schematisch dargestellt.An embodiment of the subject matter of the invention is -on the drawing shown schematically on the basis of a stuffing box to be used for hot water pumps.

Auf der Welle i sind die im Pumpengehäuse 3 angeordneten, nicht gezeichneten Laufräder befestigt. In das Gehäuse 3 ist die Stopfbüchse 5 eingesetzt, deren Packung 30 durch eine Brille 7 in ihrer Lage festgehalten -wird. Die Brille? enthält eine Vorstopfbüchse 8, welche durch eine Überwurfmutter 9 abgeschlossen ist, sowie einen Ringraum i o, der mit dem Ablauf i i für das Kühlmittel in Verbindung steht.On the shaft i are those arranged in the pump housing 3, not shown Impellers attached. In the housing 3, the stuffing box 5 is used, the packing 30 is held in place by glasses 7. The glasses? contains a Pre-stuffing box 8, which is closed by a union nut 9, and one Annular space i o, which is connected to the outlet i i for the coolant.

Über die Welle i ist eine als Körper für sich ausgebildete Büchse 12 gezogen. Zwischen der Welle i und der sie einhüllenden Büchse 12 ist ein für den Durchlauf eines Kühlmittels ausgebildeter Hohlraum vorgesehen, der durch den Kamm 14 der Pumpenivelle in Teilräume 15 und 16 unterteilt wird. Die Welle i ist mit einer Bohrung 2q. versehen, welche durch radial auslaufende Kanäle 25 und 26 .mit ,dem Hohlrauen 15 in Verbindung steht.About the shaft i is a sleeve designed as a body for itself 12 drawn. Between the shaft i and the sleeve 12 enveloping it is a for the passage of a coolant formed cavity provided through the Comb 14 of the pump level is divided into subspaces 15 and 16. The wave i is with a hole 2q. provided, which through radially tapering channels 25 and 26 .mit, the hollow roughness 15 is in connection.

Die Kühlung des Pumpengehäuses erfolgt vermittels eines durch einen Kanal 6 in einen Ringraum q. eingeleiteten und durch einen Kanal 27 aus demselben abgeleiteten Kühlmittels. Das -gegebenenfalls .durch den Spalt 23 eindringende Fördermittel wird durch die Laterne i9 und den Kanal 18 in den Ringraum .l geleitet.The pump housing is cooled by means of a through a Channel 6 into an annulus q. introduced and through a channel 27 from the same derived coolant. The -possibly .through the gap 23 penetrating funding is passed through the lantern i9 and the channel 18 in the annulus .l.

Durch die Zuleitung des Kühlmittels durch die Bohrung 2.1 wird nicht nur eine wirkungsvolle Innenkühlung der Büchse 12 und damit der ganzen Stopfbüchse bewirkt, sondern auch eine besondere Fördervorrichtung für das Kühlmittel erspart, indem durch die Drehung der Welle das durch die Kanäle 25 und 26 austretende Wasser in den inneren Teilhohlraum 1.5 gefördert und aus diesem durch Öffnungen 21 in den äußeren Teilhohlraum 16 gepreßt wird, aus -welchem es durch in der Büchse 12 angeordnete Bohrungen 28 und den Ringraum i o in die Leitung i i abfließen kann.By supplying the coolant through the bore 2.1 is not only effective internal cooling of the sleeve 12 and thus the entire stuffing box causes, but also saves a special conveying device for the coolant, in that the water exiting through channels 25 and 26 is caused by the rotation of the shaft promoted in the inner cavity 1.5 and from this through openings 21 in the outer partial cavity 16 is pressed, from which it is arranged by in the sleeve 12 Bores 28 and the annular space i o can flow into the line i i.
